The overall objective of the project is to develop a platform-based ICT system solution as a multi-sided service platform for charging services in the residential environment to implement an automated and scalable system approach for charging services. To reduce the electricity costs of the charging service at the neighborhood level, the idea is to deliver the PV energy generated in the neighborhood to electric vehicle users with energy provenance via the charging infrastructure installed in the neighborhood and furthermore to aggregate the charging points of the different multi-charging points within a neighborhood and offer the resulting control potential to the grid provider for local grid control.
The proof of energy origin to be developed by BlockInfinity is based on a tamper-proof end-to-end chain of proof that is linked to the BSI’s smart metering PKI and based on cryptographic processes – starting from the producer (e.g. PV system) to the consumer (e.g. charging point/vehicle). e.g., charging point/vehicle) – for energy quantities and properties (e.g., location, primary energy source) for e-charging services in neighborhoods, with multiple further applications in (e.g. neighborhood tenant power) and outside (e.g. green power) of neighborhoods. Specifically, the energy proof of origin is based on a smart contract stack executable on a blockchain and uses signature verification methods, zero-knowledge proofs, and homomorphic encryption for the purpose of ensuring privacy, integrity, and tamper-resistance.
In addition, other emobility-related applications that show promise in the neighborhood and can be implemented using blockchain technology, such as market communication for charging-smart supplier switching, provision of charging flexibility, charging billing, and IT support for renewable energy communities, will be investigated and evaluated.
